Abstract

The point of common coupling of a photovoltaic energy conversion system (PVES) to the utility grid is the most critical interface point where voltage sag issues arise. This paper involves a comparative evaluation of Dynamic Voltage Restorer (DVR) and Distribution Static Compensator (D-STATCOM) in mitigating the voltage sag at the point of common coupling of a photovoltaic energy conversion system integrated onto AC auxiliary distribution system in a 110 kV/13.8 kV transmission substation in the national power grid in Saudi Arabia. The voltage sag due to a three-phase short circuit at the point of common coupling of the photovoltaic system with the AC auxiliary distribution system is investigated. The results indicate that the DVR is better than the D-STATCOM in mitigating the voltage sag issue.
